WILCO AG offers a wide range of testing systems for the demanding requirements of pharmaceutical, chemical, food, packaging and automotive industries. The testing systems are ideal for all applications ranging from lab type up to fully automatic in-line testers with capacities of up to 600 products per minute.

WILCO AG has developed and patented testing systems for a wide variety of applications such as:

  • Laser based headspace gas analysis
  • The vacuum based LFC (Liquid Filled Container) leak testing method
  • Differential pressure method
  • X-Ray to detect foreign particles, deformations and other defects
  • Vision systems for inspection of cosmetic defects
  • High-speed mass spectrometry to measure very small leaks

An innovative team of highly specialised scientists and engineers constantly develop new testing technologies and integrates these into fully automatic leak testing machines and systems. The design and assembly of these machines is performed in a modern, state of the art plant in Switzerland.

Leading companies worldwide rely on WILCO testers.
